This invention relates to weather strips de-4 signed particularly for use in windows of the sliding sash type.

The primary object of the present invention is 5 to provide a weather strip for windows having sliding sash which, in addition to functioning as a weather strip, .also functions to hold the sash in various positions of adjustment without requiring the use of conventionalv counterbalance weights.

Another object of the invention is to provide a window frame structure, adapted for reception of a weather strip of theD character referred to above, which is so constucted as to facilitate assembly of the sash therein. Inthis connection metal slides are provided for the reception of the two sash members which are ordinarily provided in windows of this character, the parts forming the slides for the upper sash being separate from those forming the slides for the lower sash and having interlocking parts which provide a parting strip between the two sash members. The metal slides are formed of comparatively thin sheet metal which is somewhat resilient incharacter and the interlocking parts are so formed that the natural resiliency of the metal formation presses against the adjacent surfaces of the sash to hold the sash in firm contact with the inner and outer sash stops.

vide a weather strip comprising an elongate strip movably mountedin a groove in the side of a window frame and having spring means pressling it inwardly of the frame and into a groove in the sash. Coil springs are utilized to provide the desired pressure and in this connection the invention provides a novel and inexpensive .means for supporting the springs. With .the above and other ends in view the in- 40 vention consists in matters more particularly pointed out hereinafter with reference to the accompanying drawing, in which Y Figure 1 is a fragmental vertical section of a window;

on lines 2-2, 3 3, and 4-4 of Fig. `1;

Fig. 5 is a section similar to Fig. 2, illustrating a metal window frame, and

Fig. 6 is a section illustrating another type of 55 having two, parallel, spaced apart vertical grooves 2 and 2a formed in the inner side thereof. Se-` cured adjacent the outer edge of the frame member I is the outer sash stop 3 and adjacent the inner edge is the inner sash stop 4. A metal 60 strip 5 extends vertically of the side member I Still another object' of the invention is'to pro- Figs. 2, 3, and 4, are sections taken respectively l and has an outwardly directed flange 6 covering the inner face of the outer stop 3 an a channel formation I received in the groove 2. vThe sides of the channel formation 1 are shown as extending at right angles to the plane of the strip 5, 5 but originally these walls extend at an obtuse angle thereto so that they are slightly compressed when inserted in the groove 2. .Compressing the lchannel formation 1 in this manner induces friction with the sides of the groove 2 10 which. will hold the formation in the groove and thus retain the strip 5 against the inner face of the frame member. 'Ihe strip 5 also has a U- shaped formation 8 at its inner vertical edge, this formation extending inwardly of the window 15 opening. It will be noted, however, that the distance which the formation 8 extends into the. window opening is comparatively small.

\ A second strip 9, somewhat similar to 'the strip 5, has a channel formation l0 frictionally fitting 20 in the groove 2a, after` the manner described above with respect to the channel formation 1. The inner vertical edge of the strip 9 has a U- shaped formation II which has'an interlocking relationship with the U-shaped formation 8. 'I'he 25 formation Il extends into the. window opening `a Ysufficient distance to provide a parting strip and the lower sash l2 is mounted between the parting strip I and the inner stop 4. The up: per sash I3 is mounted between the vflange 6 and 30 the parting strip I I.

It is apparent, upon reference to Fig. 2, that thechannel formation I0 in the groove 2a holds the strip 9 from shifting laterally of the frame member I. Therefore, by forming the wall of '35 the parting strip II`which engages the sash I2 at anacute angle relative to the plane ofthe strip 9 when the sash is placed therein it tends to deform the strip and this deformation causes the parting strip to resiliently -press the sash 40 against the inner stop 4. -The window sash I2 is firmly engaged by both the parting strip and the inner stop and provides aweatherproof construction.

Received in each of the channel formations 1 45 and I0 is a weather strip. formed of sheet metal,

" and extending the entire height of the frame member I. The-weather strip has an inner wall I4 which is slightly rounded to t into a similarly shaped groove in the adjacent vertical edge ofl the sash I2 or I3,l as the case may be. 'I'he weather strip has two parallel side walls I5 slidably engaging the side walls of its channel formation 'I or I0,- as theL case may be. 1 The weather strip also has a rear wall I6, formed.

by bending the edges of the side walls l5 inwardly. Approximately intermediate its ends Ithe wall I5 has an aperture I1 through which a pin I8 extends to support the strip with respect to the side member' I, the pin I8 func- 00 .10 I5a to engage the sides of the spring support to retain it with respect toA the weather strip. In each spring support A2li two coil springs 2I are mounted, and these springs function to press the inner edge I 4 of the strip into the groove v in the adjacent edge of the sash. In addition to providing a Weatherproof construction the springs-'2| induce suicient friction between the weather strip and the sashthat the sash will remain in various positions of vertical adjustment without the use of counterbalancing weights.

It will be understood that the complete window frame comprises two frame members I and that the structure described above will be du- 26 plicated on both sides. A similar structure will be provided at the top of the window frame for the upper sash I3 and at the bottom or sill for the lower sash I2.

In assembling the above described window 30 construction the outer stop 3 is secured in place and the strip 5 is placed with its channel formation extending into the groove, the weather strip being assembled in the channel formation prior to placing the strip 5 in the frame. The sash I3 is then snapped into place between the weather strips on opposite sides of the frame. In order to place the sash I3 between the two weather strips it is necessary for the edges of the sash to clear the U-shaped formation 8 on the strips 5. This is made possible by rst placing one edge of the sash in engagement with its weather strip and then pressing upon the sash so as to compress the springs 2| so that the weather strip is forced back into thechannel formation 'I to permit the edge of the sash I3 to engagethe strip 5. At this time the other edge of'the sash may be moved past the other formation 8 and snapped into engagement with its weather strip. lAfter the sash has been snapped into place the springs 2| 50 acting'at opposite sides thereof will centralize the sash relative to the window frame. That is, there will be a small clearance between the edge of the sh 2and the adjacent strip 5 'as illustrated in 5'5 After assembly of'the sash' I3 as 'above described the strips 9 are put in placerwith the formation I I interlocking with the formation 8 and providing a vertical parting strip. The sash I2 is then snapped between the weather strips supported by the strip 9 and the inner stops 4 secured in place.- In order that it will be apparent that the weather strip above described may be used in combination with a metal window frame the same has been illustrated in Fig. 5. The metal window frame 22 is formed by rolling a strip of metal to provide a cross sectional configuration embodying two vertical channels 23 and 24` and an integral outer stop 25. The facing strip 5a having a channel formation 'la received in the channel 23 is assembled in the manner above described and a second strip 9a has a channel formation Na and a parting strip forming part IIa interlocking with a U-shaped formation la on the strip la.

weather strip.

The metal window frame structure shown in Fig. 6 shows the parting frame member for separating and supporting two adjacent sets of window sash. In this case, two vertical side members 22a and 22h are formed with channel formations 23a and 24a. for the reception of strips 5b and 9b such as above described. To hold the outer edges of the frame members 22a andv 22h together the member 22h is provided with a bead 26 over which the U-shaped formation on the member 22a ts. 'I'he'inner edges may be secured together in like manner or by use of an ornamental strip.

Although specific embodiments of the invention have been illustrated and described it will be understood that various changes may be made friction to hold said formations therein, said strips having interlocking parts retaining the same together with one of said interlocking parts comprising a parting strip, sash slidable between pairs of said strips, weather strips received in -said channel formations, and springs pressing said weather strips in'to engagement with said sash.
